Readiness and startup for Run2021 
Software update


MinutesTPC meeting January 13, 2021

 

Hardware status:

 

HV systems ok. GG drivers fixed/swapped modules and the noisy channels reported earlier is gone. Laser ok.  Will work on gas systems, ongoing plan to have Ar flowing by next mid-week, getting blue sheet by Mon 25.

Methan gas flow starting with shifts on Tuesday 26 at 8 am.

 

Alexei mentioned Jeff had asked for some positions of laser – will forward e-mail to Yuri.

 

Gene has requested sets of run with GMT trigger that was created for run20, but where commissioning was not complete. A software (trigger code had a flaw, but is now fixed).

The MTD will be available for the startup phase, and for possible other physics runs like O+O should they happen.

 

Yuri brought up that it will be very useful to have about 3 days of FF cosmics. He was requested to come with a specific goal for tracks/triggers that we can forward to ops group.

Q: When did we last have FF cosmic data?

 

Gene reminded us that DB should be initialized for this run. Will ask Irakli if he had scripts from last year to do this and get hold of them.

 

Flemming mentioned that Star ops mgt and star mgt will like to have a review for TPC focused on calibrations and tracking. As Gene pointed out this has not been done in about a decade. It will be an internal STAR committee chaired by Zhangbu.

 

Yuri informed us that there was an error in his calculations (code, not formulae) and that the

Results presented last week on asymmetric corrections are wrong. They are symmetric in East/West, Thus the issues on the alignments and calibrations still stands as un-resolved.

 

Gene has started a study of looking at residuals in low-luminosity 19.6 Gev runs and see a split between inner and outer. Seems related to padrow40 correction i.e static distortion due to the gridleak wall. Gene will present results at a later stage of the study.

Minutes:
 GMT  status was discussed. Grigory - software should be ready with very soon. It is planned to revisit the 2014 data since there are perios with difeerent luminosities. Necessity of the simulator was discussed as well.

MuMc - Yuri has provided data with fixed target simulation, plus we will test on nightly production data.

KFP - by the next week Pavol should transfer codes to Diptanil to run the D meson test.
